I'am planning to build some RF modules, so I need informations about
connectors.
I must decide between N and/or SMA connectors.
My application should lie in region some GHz.
What types of connectors should I choose?
If I will buy the connectors in small quantities (10 to 20 pieces)
where can I get it in cheap prices ?
how much power rating of your system, if the power is low, you can choose the SMA, if the power rating is high(>100W), then use the N connector, that is OK?
N type is more rugger than SMA.
N is more "intuitive" if non-expert person should connect or disconnect.
Once connected to the opposite sex, N is splash proof, but remember that N and SMA are not rated as waterproof.
The cost and the rugger index depend on metal alloy. Stainless Steel is more expensive and more robust than Brass made connectors.

All the above are good to consider. Also, N type connectors can be tightened by hand (finger tight), whereas SMA should be tightened with a torque wrench.
